SPECIFICATION forming 'part 0f Letters Patent N0. 722,607, dated March10, 1903.

Application filed August 20, 1901. Renewed July 11, 1902. SerialNo.115,219. (No model.)

.T all whom it may con/cern:

Be it known that I, ADOLPH MUELLER- WIEss, a citizen of the UnitedStates, residing at Sebewaing, in the county'of Huron and State ofMichigan, have invented new and useful Improvements inStovepipe-Thimbles, of which the following is a specification.

My invention has relation to improvements in stovepipe-thimbles; and theobject is to provide an article or device of the kind named which issimple in construction and efficient in eecting the purpose and whichmay be conveniently packed for transportation within the least possiblespace.

With these objects in view the invention consists in a new and improvedarticle of manufacture having novel constructions and combinations, aswill be hereinafter fully specified, and particularly pointed out anddistinctly claimed I have fully and clearly illustrated my invention inthe accompanying drawings,where 1n Figure l is a perspective View of myimprovedstovepipe-thimble complete. Fig. 2 is a longitudinal sectionalview showing the end of a stovepipe section inserted in the thimble.Fig. 3 is a detail perspective view of the thimble with the clamping barand bolts removed.

Referring to the drawings, A designates the body of the thimble, whichconsists of a suitable strip of sheet metal formed into a pipe orcylinder and left open at its meeting edges, which are adapted to lap oroverlie each other and are provided with suitable registering aperturesl. The outer end of the thimble is formed with an annular iiange 2, andthe inner end for a proper distance is tapered, as at 3, to enter andwedge within the pipe-hole ofthe chimney or fiue. The part 3 ispreferably crimped or corrugated, so as to take firmly in the pipe-holein the flue.

4 designates a clamping and holding plate or bar which is laid over themeeting and lapped edges of the thimble, with its inner end coincidentwith the outer or base line of the taper and extending at the front endbeyond the edge of the thimble, as at 5, to overlie the surface of apipe-section which may be inserted in the thimble. This platel or bar 4is provided with apertures 6, registering with those in the lapped edgesof the body of the thimble, and through these registering apertures areprojected headed bolts 7, entered from the inner side and provided withfastening-nuts 8, whereby the lapped edges of the thimble are clampedtogether and the bar also held in place. In the projecting end of thebar 4 is made a threaded hole in which engages a threaded fastening orholding pin 9, the point of which bears on the surface of the insertedpipe, as indicated in Fig. 2 of the drawings, and holds the thimble andthe pipe locked together.

The parts may be assembled or secured together for use by pressing themeeting edges of the thimble to make the lap, when the bolts can bepassed throughv the apertures in the lapped edges. The bar then can beplaced in position and the fastening-nuts applied. The holding-pin canthen be inserted in the projecting end of the bar, and the device isready for use. The device is then forced into the flue or chimneypipe-hole, the stovepipe inserted in the thimble, and the holding-pinscrewed down tov bear `on the pipe.

When the barrel of the thimble is in the condition indicated in Fig. 3of the drawings, withV the edges free, it will be perceived that anumberof them may be nested or telescoped and occupy but little space and inwhich condition they can be conveniently transported.

'What I claim isl. In a stovepipe-thimble, the combination of a splitcylinder of sheet metal, having its edges overlapped, a clamping memberarranged over said overlapped edges, said member having a portionextending beyond the end of the cylinder, means carried by said clampingmember adapted to engage a pipesection inserted in the thimble, andmeans passing through said overlapped edges and said member for securingthem together.

2. In a stovepipe-thimble, the combination of a split cylinder of sheetmetal having its 2 regen? inner end portion tapered and longitudinally lthe clamping-strip to engage a pipe-section lo corrugated and its edgesoverlapped, a elampand hold the thimble thereon.
